Question

question 11
humans belong to which subgroup of mammals?
○ cetaceans
○ placentals
○ marsupials
○ monotremes

Explanation:

• Cetaceans: This group includes whales, dolphins, etc. They are aquatic mammals, which humans are not.
• Placentals: Placental mammals have a placenta that nourishes the fetus during pregnancy. Humans have a well - developed placenta during gestation.
• Marsupials: Marsupials (e.g., kangaroos) give birth to relatively underdeveloped young that then develop further in a pouch. This is not the case for humans.
• Monotremes: Monotremes (e.g., platypus) are egg - laying mammals. Humans are viviparous (give birth to live young) and not egg - laying.

Answer:

Placentals
